Soil water erosion is one of the most important factors of soil
degradation. Soil erosion is a process that causes loss of big
amounts of nutrients and organic matter from the topsoil layer and
pollutes the surface water bodies. The USDA- WEPP (Wa
ter
Erosion Prediction Project erosion model) represents a new
generation technology for estimating soil loss by water erosion and
sediment delivery from hillslopes and small watersheds. The main
purpose of this study was evaluating the capability of WEPP model.
